Coming up Aces: Biodiesel, Renewable Diesel and Sustainable Aviation Fuel in the Age of Decarbonization

Jan 18 — 8:30 AM-10:00 AM PST

The year 2022 dawns with exciting prospects for low carbon fuels like biodiesel – perhaps unlike anything we’ve seen in our 30-year history. Renewable diesel is also betting on success, with billions of dollars in planned projects. Plus, sustainable aviation fuel looms on the horizon. How will feedstock, technology and geography shuffle the deck during the next decade of renewable fuels production? As major corporations and governments go “all in” on net zero carbon, business models in the traditional petroleum sector and beyond will likely experience disruption in 2022 and beyond. Our expert panel will tackle the question: How can these three low carbon fuels work together?
